Feature:1. SAFE AND FLAME RETARDANT: Protector adopt PC flame retardant material, with overvoltage protection, undervoltage protection and voltage display(voltage measurement), more safe and reliable to use2. INTELLIGENT ADJUSTMENT: Multi function protector provide safe protection for electrical appliances, manual adjustment of overvoltage, undervoltage, overcurrent protection value3. EFFECTIVE PROTECTION: Over under voltage protective device can prevent unstable voltage frequent on and off to cause additional damage to electrical appliances, to achieve secondary protection4. DELAYED POWER ON: The power supply will be restored automatically after 1‑600S after the voltage is stabilized, which can protect your appliances well5. THREE DISPLAY: Current limit protector display voltage, current, KWH, more intuitive and convenient reading6. MULTIPLE FUNCTIONS: The self resetting current protector has the functions of reset mode selection, fault query and factory recoverySpecification:Item Type: Over Under Voltage ProtectorMaterial: PC flame retardantRated Power Supply Voltage: AC220VOperating Voltage Range: AC80V-400V (single item)Rated Frequency: 50/60HzCurrent (> A) Setting Range: 1-63AOvervoltage (> U) Setting Range: AC230-300VUndervoltage (< U) Setting Range: AC210-120VKWH Protection Value: 1-9999Rated Current: 63A> U And < U Trip Delay: 0.5SReset Or Startup Delay: 1-600SVoltage Measurement Accuracy: 1% (not more than 1% of the total range)Rated Insulation Voltage: 400VOutput Contact: 1NOElectrical Life: 100000Mechanical Life: 1000000Protection Level: IP20Pollution Level: 3Altitude: ≤2000meterOperating Temperature: -50℃-55℃Humidity: ≤50% at 40℃(no condensation)Storage Temperature: -30℃-70℃Product Features: 1.
